Multiple modern applications of electronics call for inexpensive chips that can perform complex operations on natural data with limited energy. A vision for accomplishing this is implementing hardware neural networks, which fuse computation and memory, with low cost organic electronics. A challenge, however, is the implementation of synapses (analog memories) composed of such materials. In this...

Intracellular neural recording is a technique that has been under development for many years, yet still remains fragile and difficult, and requires immobilization of the neurons being recorded. We are developing a system of implantable silicon chips that will intracellularly record, and locally store, the neural signaling. The principal reason we are doing this is to record from intact, mobile ...

The Adaptive Solutions CN APS architecture chip is a general purpose neurocomputer chip. It has 64 processors, each with 4 K bytes of local memory, running at 25 megahertz. It is capable of implementing most current neural network algorithms with on chip learning. This paper discusses the implementation of the Back Propagation algorithm on an array of these chips and shows performance figures f...

Address-event representation (AER), originally proposed as a means to communicate sparse neural events between neuromorphic chips, has proven efficient in implementing large-scale networks with arbitrary, configurable synaptic connectivity. In this work, we further extend the functionality of AER to implement arbitrary, configurable synaptic plasticity in the address domain. As proof of concept...

SEGMENTATION J org Kramer1, Rahul Sarpeshkar2 and Christof Koch3 California Institute of Technology, Computation and Neural Systems 139-74, Pasadena, CA 91125 [email protected] [email protected] [email protected] ABSTRACT Two analog integrated circuits that locate velocity discontinuities in a one-dimensional image are presented. Each circuit combines the image-sensing stage ...

Chemotaxis inhibitory protein of Staphylococcus aureus (CHIPS) is an exoprotein produced by several strains of S. aureus, and a potent inhibitor of neutrophil and monocyte chemotaxis toward C5a and formylated peptides like fMLP. These chemoattractants act on their target cells by binding and activating the C5aR and formylated peptide receptor (FPR), respectively. In the present report, we exami...

The use of food products designed to mimic the sensory properties of sweet and fat while providing fewer calories has been promoted as a method for reducing food intake and body weight. However, such products may interfere with a learned relationship between the sensory properties of food and the caloric consequences of consuming those foods. In the present experiment, we examined whether use o...

The objectives of this study were to determine the frying stability of soybean oil (SBO) treated with a natural citric acid-based antioxidant, EPT-OILShield able to withstand high temperatures and to establish the oxidative stability of food fried in the treated oil. Soybean oil with 0.05% and 0.5% EPT-OILShield and an untreated control SBO were used for intermittent batch frying of tortilla ch...

Background: Thirst is the most common complaint of patients undergoing hemodialysis with stimulating the patient to drink more fluids result in intradialytic weight gain. Thirst leads to some complication including heart problem which is one of the most common causes of death in these patients. Aim: To determine the effect of ice chips on thirst and fluid intake of patients undergoing hemodialy...

The objectives of this study were to determine the effect of using corn stover or three different wood-based bedding materials (kiln-dried pine wood chips, dry cedar chips, or green cedar chips) on airborne concentrations of NH, total reduced sulfides (TRS), CO, CH, and NO above lab-scaled bedded manure packs. Four bedded packs of each bedding material were maintained for two 42-d periods. Airb...
